onkeyup="this.value = this.value.replace(/,/g,'.')" with php echo' '
提问by user2465936
In input field need to replace ,with ..
在输入字段中需要替换,为..
With HTM such code is working onkeyup="this.value = this.value.replace(/,/g,'.')"
使用 HTM 这样的代码正在工作 onkeyup="this.value = this.value.replace(/,/g,'.')"
But need to use in php (with echo) like this:
但需要在 php 中使用(带回声),如下所示:
echo '<input type="text" name="amount_1" onkeyup="this.value = this.value.replace(/,/g,'.')" style="width:53px;"></input>';
With php does not work. If use this this.value.replace(/,/g,/./)then ,is replaced with /./.
用 php 不起作用。如果使用它,this.value.replace(/,/g,/./)则,替换为/./.
Tried (/,/g,"/./"), (/,/g,/"."/), (/,/g,.)nothing works (I mean ,does not change to .).
试过(/,/g,"/./"),(/,/g,/"."/),(/,/g,.)实在不行(我的意思是,不改变.)。
Any ideas?
有任何想法吗?

You have to escape the 'with a backslash in your PHP code.
您必须'在 PHP 代码中使用反斜杠进行转义。
echo '<input type="text" name="amount_1" onkeyup="this.value = this.value.replace(/,/g,\'.\')" style="width:53px;"></input>';
Otherwise you are cuting your string into to pices an put it together with the point.
否则,您将把您的绳子切成小块并将其与尖端放在一起。
